Subject Index SummariesGrasslands (Biomass Ė Individual Species): A review of the recently published scientific literature suggests that earthís grassland plants will respond positively to increases in the airís CO2 content by producing more biomass, thereby inducing a negative feedback phenomenon that should help to slow the rate-of-rise of the atmosphereís CO2 concentration as some of the extra biomass is incorporated into the soils of the grassland ecosystems.

Temperature Trends -- Africa: Analyses of historic temperature trends in Africa reveal the presence of a Medieval Warm Period and Little Ice Age that may have been caused by variations in solar activity.

Current Journal ReviewsTropospheric Ozone and Climate Forcing: New estimates of the radiative forcing of climate due to the historical increase in tropospheric ozone over the period of the planetís industrialization suggests that this greenhouse gas is responsible for a much larger portion of the increase in air temperature observed over this period than has commonly been believed.

Rainfall Trends in East Asia: Atmospheric CO2 concentrations have been rising since the inception of the Industrial Revolution, providing plenty of time for the increased monsoonal rainfall predicted by climate alarmists to occur. Over a century of data from over a hundred east Asian weather stations now allow this hypothesis to be tested.

Effects of Elevated CO2 and Soil Nitrogen Stress on Sunflowers: Some plants respond equally well to atmospheric CO2 enrichment under conditions of both low and high soil nitrogen content, while others exhibit reductions in growth response when soil nitrogen concentration is sub-optimal. How do sunflowers do in this regard?
